The public service broadcaster engaged in a "major breach" of media regulations by omitting to mention that the narrator of a documentary about Gaza was the offspring of a Hamas official, as determined by UK media regulator Ofcom.
An probe by Ofcom into the programme Gaza: How to Survive a Warzone has determined that the documentary was "significantly deceptive".
The BBC's director general had previously apologised, stating there had been "a serious error in relation to truthfulness".
Ofcom has ordered the broadcaster to air a peak-time statement about its decisions.
"As this represents a major infringement of our code, we are directing the corporation to air a statement of our conclusions against it on BBC Two at 21:00, with a date to be confirmed," the statement read.
'Possibility to Erode Trust'
The authority's statement stated: "Our investigation concluded that the programme's omission to reveal that the presenter's father held a post in the Hamas-run government was materially misleading.
"Consequently that the viewers did not have vital facts which may have been very significant to their judgment of the presenter and the content he provided.
"Confidence is at the heart of the connection between a television network and its audience, particularly for a national broadcasting corporation such as the public broadcaster.
"This error had the risk to erode the significantly high levels of credibility that viewers would have put in a factual film from the broadcaster about the Gaza conflict."
The programme was withdrawn from the online platform in February after the presenter's personal associations were revealed, and in this past July an internal BBC review concluded it infringed the organization's content policies on accuracy.
A corporation official commented: "The regulator's decision is in line with the conclusions of Peter Johnston's review, that there was a major oversight in the film in relation to the broadcaster's journalistic policies on accuracy, which reflects clause 2.2 of the authority's broadcasting regulations.
"We expressed regret for this and we comply with Ofcom's decision in its entirety. We will adhere to the directive as soon as the date and language are finalised."
